Polyethylene Glycol-600 as PCM to Enhance Efficiency of Thermal Device

PCMs are divided mainly into organic and inorganic materials [9,10,11]. Many researchers have described about PCMs and their types, Researchers have found that organic PCMs properties and characteristics are more advantageous than inorganic PCMs. Organic PCMs having high latent heat, low volume change, less corrosive, high chemical stability, high thermal stability than inorganic PCMs. In recent times, studies of PCMs are more attractive in the respect of their melting point temperature as useful for thermal energy storage. The melting point is main criteria in the selection of PCMs according to different type of applications. Some researchers have investigated the addition of PCM in different cold storage systems and units in order to enhance food quality and, to reduce electricity consumption during storage and transportation [ref]. Also several applications for thermal protection of biomedical products (such as organs and blood) during transport and storage have been studied over the years [ref]. In these applications the PCM are normally encapsulated in containers, hence the interest remains in designing a light weight, high conductive, non-corrossive, and low cost container.
